Why NOT choose cloud server provider snapshots and choose SimpleBackups instead?
In fact, for this one, we recommend that you actually have both, your own database and file backups in addition to snapshots from your web host. This is called a virtual machine snapshot.
All server providers offer automated backups of your entire server for a fee, but what happens when you delete your server by mistake? Or if some files were deleted by mistake from your site?
Certainly you are not going to restore your entire server snapshot just to get the files back.
Additionally, server snapshots do not really back up your database (unless it's on the same server, but to restore a database you will need to restore the entire server snapshot on a new instance) and won't allow an individual database restore.
You can only restore snapshots of the entire server, not individual files.
